This is what the historic cold snap looks like from a satellite

It is very cold outside. The kind of cold with life threatening wind chills. A historic cold outbreak.

Winter is normally cold, but starting Sunday tundra-like temperatures are poised to deliver a rare and potentially dangerous sledgehammer blow to much of the Midwest, driving temperatures so far below zero that records will shatter. The National Oceanic and Atmospheric Administration took a satellite photo of the snow and cold stretching from the Midwest to New England.

One reason for the cold? A “polar vortex,” as one meteorologist calls it, which will send cold air piled up at the North Pole down to the U.S., funneling it as far south as the Gulf Coast.

The temperature predictions are startling: 25 below zero in Fargo, N.D., minus 31 in International Falls, Minn., and 15 below in Indianapolis and Chicago. At those temperatures, exposed skin can get frostbitten in minutes and hypothermia can quickly set in because wind chills could hit 50, 60 or even 70 below zero.
